The embodiments are described below in order to explain thepresent invention by referring to the figures.

Hereinafter, an exemplary embodiment of the present invention will bedescribed in detail with reference to the accompanying drawings. Anobject, a characteristic, and an effect of the present invention will beeasily understood through the exemplary embodiments related to theaccompanying drawings. However, the present invention is not limited tothe exemplary embodiments described herein, and may be applied andmodified in various forms. Rather, the exemplary embodiments below areprovided so as to make the technical spirit disclosed by the presentinvention be more clear, and further, sufficiently deliver the technicalspirit of the present invention to those skilled in the art.Accordingly, it shall not be construed that the claims of the presentinvention are limited to the exemplary embodiments described below. Inthe meantime, the drawings suggested together with the exemplaryembodiment below are somewhat simplified or exaggerated, and likereference numerals in the drawings designate like elements.

FIG. 1 is a perspective view illustrating a packaging pouch according toan exemplary embodiment of the present invention, FIG. 2A is across-sectional view illustrating a surface taken along line I-I′ ofFIG. 1, and FIG. 2B is a cross-sectional view illustrating a surfacetaken along line II-II′ of FIG. 1.

Referring to FIGS. 1, 2A, and 2B, a packaging pouch 100 includes a firstcover part 10, a second cover part 50, and coupling parts 80.

The first cover part 10 has a packaging area PA and a sealing area SAsurrounding the packaging area PA. Further, the second cover part 50faces the first cover part 10, and is coupled to the first cover part 10in the sealing area SA.

In the exemplary embodiment of the present invention, the packaging areaPA may be defined along a circumference of the first cover part 10, andthus the second cover part 50 is coupled to the first cover part 10along the circumference of the first cover part 10. Further, the firstand second cover parts 10 and 50 are not coupled to each other in thepackaging area SA, so that it is possible to provide an accommodationspace for accommodating a product between the first and second coverparts 10 and 50 so as to correspond to the packaging area SA, and theaccommodation space may be sealed from the outside according to thecoupling of the first and second cover parts 10 and 50 in the sealingarea SA.

In the meantime, a cutoff portion CP and a perforated line CL is formedin the first cover part 10 and the second cover part 50. The cutoffportion CP is formed by partially removing at least one side of thefirst and second cover parts 10 and 50, and the perforated line CL is incontact with the cutoff portion CP to cross the packaging area PA andthe sealing area SA. Accordingly, a user may easily open the packagingpouch 100 along the perforated line CL by using the cutoff portion CP.

The coupling parts 80 are arranged to be spaced apart from each other onthe first cover part 10 and the second cover part 50 in the packagingarea PA to couple the first and second cover parts 10 and 50 to eachother. The coupling parts 80 may be disposed while being adjacent to thecutoff portion CP. Structures of the coupling parts 80 will be describedin more detail with reference to FIGS. 2A and 2B.

The coupling parts 80 are interposed between the first cover part 10 andthe second cover part 50, and the coupling parts 80 include firstcoupling members 82 and second coupling members 81. The first couplingmembers 82 are provided while being spaced apart from each other on thefirst cover part 10, and the second coupling members 81 are providedwhile being spaced apart from each other on the second cover part 50 tobe one-to-one coupled to the first coupling members 82.

In the exemplary embodiment of the present invention, as illustrated inFIG. 2B, the first coupling members 82 may have a shape protruding fromthe first cover part 10, and the second coupling members may havecoupling recesses 83 accommodating the first coupling members 82.However, contrary to the exemplary embodiment of the present invention,the first coupling members 82 and the second coupling members 81 may becoupled to each other by other methods, such as an adhesive, a zipper,and a Velcro.

Further, in the exemplary embodiment of the present invention, asillustrated in FIG. 2B, the first cover part 10 may include a first film11 and a second film 12 which are stacked each other, and the secondcover part 50 may include a third film 51 and a fourth film 52 which arestacked each other. In this case, the first film 11 and the third film51 stacked at the innermost sides of the first and second cover parts 10and 50 to be coupled to the first and second coupling members 82 and 81may include Linear Low-Density Polyethylene ((hereinafter, referred toas “LLDPE”) or Casting Polypropylene (hereinafter, referred to as“CPP”), and the second film 12 and the fourth film 52 which are incontact with the outside may include a nylon film, an orientedpolypropylene (OPP) film, or a polyethylene terephthalate (PET) film.

In the case where the film 11 and the third film 51 include LLDPE andCPP, a sealing process between the first coupling members 82 and thefirst film 11 and a sealing process between the second coupling members81 and the third film 51 may be easily performed by using heat andpressure, and excellent sealing strength after the sealing process maybe achieved. Further, LLDPE and CPP have excellent cold resistance andimpact resistance, so that even though the packaging pouch 100 (seeFIG. 1) is kept in a refrigerator or a freezer, reliability of thepackaging pouch is prevented from deteriorating.

In the meantime, as described above, the coupling parts 80 are arrangedwhile being spaced apart from each other, so that an exhaust hole 85 isformed between the adjacent two coupling parts. A space between thefirst and second cover parts 10 and 50 is widened so as to correspond tothe exhaust hole 85, so that air flowing into the packaging pouch 100may be easily discharged to the outside through the exhaust hole 85.

FIG. 3A is a perspective view illustrating the packaging pouch, a partof which is cut along the perforated line of the packaging pouch of FIG.1, so that an entrance is opened, FIG. 3B is a view illustrating a statein which the entrance of the packaging pouch illustrated in FIG. 3A isblocked by the coupling parts, FIG. 3C is an enlarged top plan viewillustrating a part of the packaging pouch illustrated in FIG. 3B, andFIG. 3D is a perspective view illustrating a state in which contents arepackaged within the packaging pouch illustrated in FIGS. 3A and 3B.

First, referring to FIGS. 3A and 3B, a part of the sealing area SA ofthe packaging pouch 100 is removed along the cutoff portion CP and theperforated line (CL of FIG. 1) aforementioned with reference to FIG. 1,and the fastening between the first coupling members 82 and the secondcoupling members 81 is released, an entrance 88 of the packaging pouch100 is opened. Accordingly, the user may obtain contents accommodatedinside the packaging pouch 100 through the entrance 88, or insert thecontents into the packaging pouch 100 through the entrance 88.

Further, the entrance 88 may be blocked by fastening the first couplingmembers 82 and the second coupling members 81 of the coupling parts 80with each other. In this case, the coupling parts 80 are arranged whilebeing spaced apart from each other with an interval, so that even thoughall of the first and second coupling members 82 and 81 are coupled, aninternal side of the packaging pouch 100 is not completely blocked fromthe outside by the exhaust hole 85.

Accordingly, as illustrated in FIG. 3C, air AR inside the packagingpouch 100 may be discharged to the outside through the exhaust hole 85defined between the adjacent two coupling parts 80, and thus it ispossible to prevent an increase in an inside volume of the packagingpouch 100 by the air AR.

Referring to FIG. 3D, according to the aforementioned configuration ofthe packaging pouch 100, the user may package contents by using thepackaging pouch 100 in a sequence of obtaining the contents packagedwithin the packaging pouch 100 after securing the entrance 88 byremoving the part of the packaging pouch 100 along the perforated line(CL of FIG. 1), inserting the remaining contents into the packagingpouch 100 through the entrance 88, and blocking the entrance 88 by usingthe coupling parts 80. Particularly, in the case where the packagingpouch 100 is folded into a multistep and stored at the storage place inthe state where the first and second coupling members 82 and 81 arefastened with each other, the air AR may be more easily discharged tothe outside through the exhaust hole 85.

The present invention has been described with reference to the exemplaryembodiment, but those skilled in the art may understand that the presentinvention may be variously modified and changed within the scope withoutdeparting from the spirit and the area of the present inventiondescribed in the accompanying claims.
